This research study analyzes how the predictor variables sensing-intuitive learning style, verbal-visual learning style, gender, major, and degree level of adult learners predict student intrinsic motivation-to know, extrinsic motivation-external regulation, and amotivation to pursue an online graduate degree. The primary research question states: Do the predictor variables of degree level, major, gender, sensing-intuitive learning style, and verbal-visual learning style, taken collectively, result in a statistically significant prediction of the outcome variable of intrinsic motivation-to know? A nonexperimental multiple regression analysis was used. The target population for this study was adult students 25 years old or older pursuing an online graduate degree at the master's or doctorate level, living in the United States, currently enrolled in an online graduate program, and majoring in computer science, business, or psychology, and identifying as a man or woman. The sample of 85 students were selected utilizing a non-probability convenience sampling procedure. The researcher coded the data and calculated the scores for each participant for the Index of Learning Styles (ILS) and the Academic Motivation Scale (AMS-C) subscales used in the study. The findings displayed degree level, major, gender, sensing-intuitive learning style, and visual-verbal learning style combined were not predictors for the outcome variables intrinsic motivation-to know, extrinsic motivation-external regulation, and amotivation. Statistically significant results were displayed for gender on amotivation, R[superscipt 2] = 0.095, F(5, 79) = 1.654, p = 0.029. Future research on a similar topic using an experimental study could potentially yield causal results. [The dissertation citations contained here are published with the permission of ProQuest LLC.
